Zveri - Krestnyy Khod: The Beast that Accompanied me On My Journeys (我が旅路に従え獣,Ware ga Tabiji ni Shitagae Jū?) is a Noble Phantasm of Ivan the Terrible.
Crucession of the Divine Beast. This is the ascension path he (believe) would one day walk to heaven. Therefore standing in his way is equivalent to rebellion against Tsar and sacrilege to God. The Tsar would temporarily retrieve his beast form and mercilessly destroy the enemies.
